Furnace tube inspection unit

Generally, provincial special equipment inspection centers that have the appropriate inspection qualifications can handle such requests.

We are looking for the Provincial Special Equipment Inspection and Research Institute. Generally, special equipment is inspected by units affiliated with the provincial quality and technical supervision bureau. The Provincial Special Equipment Inspection and Research Institute is a special inspection agency under the Provincial Quality and Technical Supervision Bureau.

I believe that the inspection departments of some large boiler manufacturers (such as Class A boiler manufacturers), as well as the organizations responsible for the supervision and inspection of boilers and pressure vessels mentioned on the 3rd floor (such as provincial special equipment testing institutes), can all carry out this task.

Currently, the material used for the conversion tubes in hydrogen production furnaces is generally HP-Nb, with the manufacturing process being centrifugal casting. The furnace tube is columnar-grained austenitic stainless steel with a rough surface and large grains. The failure of furnace tubes during operation is caused by high-temperature creep cracks, creep swelling, and material degradation, which gradually lead to the formation of macroscopic cracks and eventual tube rupture. Therefore, it is crucial to find an appropriate detection method. Given the special properties of the materials and structure, conventional non-destructive testing standards and methods are not applicable; in other words, ordinary testing agencies do not have any effective solutions for this issue. At present, the company that conducts the most and best inspections of hydrogen production furnace tubes in China is Nanjing Chixin Technology Co., Ltd.

Hydrogen production converters in refineries and chemical plants are the most important equipment in hydrogen production systems, and the furnace tubes constitute the core of these devices. They are generally cast by centrifugation using heat-resistant steel materials such as HP40Nb and HP40Nb-M. Damage to any one of the furnace tubes forces the entire installation to stop operating, resulting not only in significant economic losses but also a high risk of injuries or fatalities. Therefore, based on the types and characteristics of furnace tube damage, it is very important to evaluate the safety and reliability of the furnace tubes using non-destructive testing methods. During equipment shutdown for maintenance, each furnace tube is inspected individually, and a comprehensive technical assessment is conducted to determine the degree of damage to each tube. This approach enables prevention and early prediction, which is essential to ensure the safe and stable operation of the equipment in the next cycle.
